Identification:
Rather large. Males above look like icarus (Almindelig Blåfugl) but has a wider black rim to both wings. The female has a broad diffuse black rim along the outer margin of the forewings, and extensive diffuse black along the frontal part of the hindwing. Below both sexes show a rather clean grayish base color with large black spots encircled with white on the forewing and much smaller similar spots on the hindwing. The basal part of the hindwing shows a bluish turquoise color characteristic for the species.

Distribution:
Algeria, Tunesia, Europe, C Asia to Amur.

The species follows an ant-related larvae symbiosis.
